Don't really do these things at a wedding, but they're just fun to imagine- right!? =)

Show up with a Baby and tell everyone it belongs to the newlyweds!

Cover yourself with glue to improve your chances of catching the Bouquet

Tell everyone that you knew the Bride before the Sex-Change

Instead of a Gift, give the newlyweds a chewed pencil each and a scrap of paper- and tell them to write to you from their honeymoon destination

When the organist starts playing the wedding march, push them out of the way and start playing Abba's "I Do I Do I Do"

Propose a Toast to the Bride's Nosejob

Switch around all the cards on the Wedding gifts

Walk up to various guests and demand to see their invitations

During the service, run up to the alter and start clicking away on your camera like a Model Photographer, and say stuff like "Okay! That's Great! Hold it right there! Just turn this way a bit more! Beautiful! Hold it!"
